    ► APEX | EC-7 Wheels: Now Available!



    APEX EC-7 Wheels

    APEX is proud to introduce its new EC-7 wheel. This new wheel addresses the concerns of more and more racers and track day enthusiasts: long term durability, fitment, and performance. With the increase of faster and heavier cars being used in racing, HPDEs, and spirited driving, the EC-7 was designed and engineered to handle extreme abuse on track and street, offer a wide range of direct fitments, while still producing a lightweight wheel.

    A performance-optimized build begins with the perfect wheel fitment. Without the perfect offsets, maximum tire widths and the potential of your car are always compromised. With this in mind, the EC-7 has three unique face profiles ranging from shallow to deep concavity resulting in 14 unique 18" sizes, and 10 unique 19" sizes. This wide range of fitments allows for vehicle-specific caliper clearance, offsets, and tire widths, creating the most optimal setup possible.

    The Good Stuff




    1. They Fit Everything
    The EC-7 adds 7 new BMW sizes not available in the ARC-8 design. The 3 face profiles offer maximum concavity and reduced weight. This avoids the common adaptation of a single face profile for unintended fitments or dependency on spacers.

    2. Factory Support
    Like all our APEX wheels, The EC-7 supports all OEM hardware like OEM Roundel center caps, wheel lugs, valve stems, and TPMS sensors. No centering rings are needed either, as all of our 5x120 wheels use a 72.56mm center bore.

    3. Brake Clearance
    If the spokes of a wheel don't clear your brake calipers, then the wheel can't be used at all. We made sure all 18" APEX EC-7 wheels can properly clear OEM steel brakes without spacers. Because of the large variation in clearance needs, we produced the EC-7 wheel using three unique face profiles. When the correct profile is used for each specific vehicle application, all big brake kits can clear the spokes spacer-free, including the Brembo 6-piston 380mm kit.

    4. Concavity
    Multiple face profiles are utilized to maximize spoke concavity and reduce weight on the EC-7 design. This allows us to maintain our great brake clearance and concave spoke curvature.


    Designed for the Performance Enthusiast

    Light-weight
    Flow-forming allows for a significant reduction in rotational mass by reducing barrel weight. This manufacturing technique allows our wheels to be almost as light as a traditional forged wheel, but without the significant increase in price.

    Strength
    Track duty requires a wheel that can handle the punishment of high lateral G’s, hitting berms, and every once in a while, a small off track excursion. Spoke and barrel design are a major factor in wheel strength. The flow-forming technique uses high pressure disks/rollers to roll the wheel’s barrel into its final shape. This gives the barrel the same strength properties as a forged wheel, since monoblock wheels go through a similar step to form their barrels. We design our spoke dimensions to help evenly distribute loads from the barrel to the center of the wheel. The lack of a front lip, and spokes directly connecting to the edge of the wheel, also add increased strength to the outer lip of the wheel.

    Chassis-Specific Fitments
    Stretched rubber, narrow tires, and fender rubbing are not elements to look for in a competitive wheel/tire setup. All of our wheels were designed with offsets that allow for proper fitment of extreme summer, and r-compound tires without the need for spacers or fender rolling. This means keeping the tire under the fender, and away from suspension components. Track oriented wheel widths are also important as they provide proper sidewall support under hard cornering. Too much rubber for a wheel results in excessive sidewall deflection, which translates into sloppy and delayed turning response.

    Multiple Fitment Options
    Most BMWs come with a staggered setup from the factory. Some choose to keep their car this way, while others like to switch out for an easy-to-rotate, square/neutral setup. This is generally based on driver’s preference and consideration of tire costs. Most BMW chassis benefit from being able to fit both square and staggered setups with relative ease. 9.5” or 10”-wide square setups are great for budget minded enthusiasts who want to extend their tires life by rotating between events, in addition to preferring the feel of a square setup. Square setups are popular on all models for track use due to the significant increase in front grip and turn-in response. Some owners comment that due to the extra power of their cars, a square setup will lean towards oversteer. For those who prefer more rubber in the rear, a staggered setup is the way to go. Wheels up to 11" wide are available for rear fitment. These can be combined with 9.5” or 10” fronts for a bolt-on spacer-free staggered setup.

    BBK Clearance
    Many owners install Big Brake kits on their cars. Having a smaller-diameter wheel that can clear large calipers is a must. Due to the low-offset nature of many BMWs, there are no clearance issues with the concave spokes. Barrel clearance was increased during the design phase to accommodate both StopTech and Brembo's 380mm kit.


    The APEX Standard



    1. FEA Optimization
    We took more time than ever before on this step, revising and iterating our design to reduce weight as much as possible. After countless iterations we removed material from the sides of the spokes in a way that allowed us to increase strength over our previous designs.

    2. Always Flow Formed
    All APEX wheels feature Flow-Formed construction that utilizes rotary forging to produce a strong and lightweight barrel. The EC-7 is no exception.

    3. True JWL & VIA Certification
    Strength needs to be certified. Our wheels were not simply FEA tested in a computer simulation, or in-house tested to an unregulated standard. We conduct real-world crush-testing and all of our wheels conform to Japan’s JWL standard, as well as being 3rd-party tested by the VIA. All of our wheels carry a 690KG load rating.

    Fast ones.
    Those look great! 18x9 up front on E36 is sweet.

    They do look incredible! Maybe this summer I'll snag some 18x10s and run 265s on my e36, since the 18x10et43 rear and 18x10et33+12mm spacer front would work perfectly!

    For your 2003 325xi with H&R springs, the recommended fitment for the EC-7's would be the 18x8.5" ET35 and 18x9.5" ET43 which provides a Profile 1 front and Profile 2 rear for that staggered look and a bit more concavity in the rear. This setup can be used with 235/40/18 and 255/35/18 sized street tires on your car. If you would prefer a squared fitment, you can use the 18x9" ET42 all around with 245/35/18 sized street tires as well.

    That sounds like a great idea, we'd love to see your E36 running that wide of a wheel.

    Are these going to be made in 17's in the future? (For some of the guys that would rather run 17's and not get the ARC-8)

    We do not currently have plans to make the EC-7's in the 17" diameter at this time, but if we decide to in the future, we will surely announce it on the forums and on our website.

    Plenty of EC-7s in various E36 fitments available in stock and ready to ship.
    Any mods needed to run this set up ? I would love to do this.

    For this front fitment in this particular photo, we used a 225/40/18 Yokohama S-drive, which is much narrower than what we would normally recommend. Ideally a 245/35/18 or wider tire would be installed on a 9" wheel to take advantage of the wheel's width, along with at least -2.5 degrees of camber obtained through camber plates or swapping your strut hats. Our car had -3.5 degrees camber in the front but much less could have been used. For those willing to stretch tires, these 9" wheels can be used with narrow tires for an aggressive street fitment with little to no added negative camber.

    The rear is using the 18x9.5" ET43 wheel with a 255/35/18 Yokohama S-drive street tire. The fenders are rolled on this car and that would still be a requirement when using these wheels due to the added width. There is a chance that some street tires in the 245/35/18 size would work on the rear without the requirement of a fender roll, but you'd have the same sized tire all around in this case and the tires would be slightly undersized for the 9.5" width.

    Have you had anyone run the 18x10 et33 yet ? I would consider that and a pair of flares out back with the 18x9 up front. Im running a street car but would love the traction and just the raw look of it. I am running ISC coil overs with the camber plates but i would even flare the front or try to pull them.

    Hmmm not a fan of the pulled but it looks like I can make it work with flares. Maybe even push to 18x11. I would still do the 18x9 up front most likely unless having the backs that much wider would effect any handling characteristics.

    The wider the rear wheel is compared to the front, the more understeer the car faces where it would push through a corner at the limit. Most people prefer the squared setups so that they can make the car feel more neutral and reduce the amount of understeer that the car has, especially for performance driving. For street driving, most people do try to keep the stagger at one inch as that's how most BMW staggered wheels come from factory.

    Ah ok. I might look at doing the 18x10 and 18x9 the. Or something. Need to get prices through bimmerworld on them.

    Fender rolling would be dependent on the fitment and tires you decide to go with. The conservative fitment of 18x8.5" ET35 and 18x9" ET42 EC-7's with 235/40/18 and 255/35/18 street tires would not require a fender roll, but the wider & more aggressive 18x9.5" ET43 rear would require it. Did you have a particular fitment in mind?

    In order to fit the 18x10" ET43 with a 265/35/18 or 275/35/18 tire on the rear of the E36 M3, you would need to pull the fenders in order to have the proper fender clearance. It is a difficult fitment, but can be done if you are willing to work on the rear fenders to create enough clearance for the tires.

    How much of a pull would be needed. I might do some flares still.

    It would be a decent fender pull, the amount will be dependent on the tire that you decide to choose to use. Fender flares would definitely be the better solution.
